1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The virus-encoded viroporins are known to modify membrane permeability and play an essential role in virus budding. Here, a comparative analysis of the membrane permeabilization capacity of a number of viroporins was performed in baby hamster kidney cells. Synthesis of 6K protein from Sindbis virus, E from mouse hepatitis virus, M2 from influenza A virus, and 2B and 3A from poliovirus enhanced membrane permeability to different extents. We show that two proteins from hepatitis C virus, p7 and NS4A, also display viroporin activity to a level comparable to 6K protein. In addition to their capacity to disrupt ionic cellular homeostasis and promote bacterial cell lysis, the expressed viroporins were able to induce cell death. Degradation of internucleosomal DNA and generation of apoptotic bodies were observed upon viroporin expression. Consistently, cleavage of translation initiation factor 4GI and poly-(ADP-ribose) polymerase indicated activation of effector caspase-3. We found that poliovirus 2B localizes partially in mitochondria and induces an anomalous perinuclear distribution of these organelles. Mitochondria morphology was also altered after expression of other viroporins. Finally, detection of cytochrome c release from mitochondria suggests involvement of the mitochondrial pathway in viroporin-induced apoptosis. These findings suggest that viroporins induce caspase-dependent programmed cell death.
